WILBUR MARVIN CARPENTER, OF ST. LOUIS, MISSOURI.

TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 437,090, dated September 23,1890. Application filed September 21, 1886. Serial No. 214,198- (No model.)

To all whom it may concern.-

Be it known that I, WILBUR MARVIN GAR- PENTER, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented a new and useful Paper-Carriage and Inking-Ribbon Motor for Type-\Vriting Machines, of which the following is a specification.

My invention relates to improvements in feeding paper and inking ribbon simultaneously to short-hand machines, type-writers,

. and other machines, and has for its objects,

first, to enable the operator (when using sheets in place of paper ribbon) to Write a whole page by one adjustment of the paper, instead of having to adjust the paper for every line; second, to afford facilities for applying and removing the paper with celerity, and, third, to afford a simple and efficient Way of moving the inking-ribbon in connection with the paper.

The idea governing the designing of this machine is to place several sheets of paper around a cylinder made to revolve by a kind of clock-work about a stationary rod having a screw-thread running nearly its whole length. At each revolution of the cylinder the screw causes it to travel (under the inking-ribbon) parallel to its axis a distance equal to the breadth of a printed line and the breadth of space between lines, and these two motions continue at the pleasure of the operator or until the sheet of paper is filled, when the operator removes the sheet by means of a pair of forceps designed especially for this purpose and slides the cylinder back to the starting-point ready for the next sheet to be printed or written upon.

The mode of preparing the paper and the parts of machinery above alluded to, together with other mechanism necessary to accomplish the results set forth, are fully described in the following specification and illustrated in the accompanying drawings, in which- Figure 1 is a longitudinal section taken in the line w y, Fig. 5; Fig. 2, an end elevation of the mechanism which propels the papercarriage; Fig. 3, a perspective view of prepared edges of paper; Fig. 4:, a variation of the screw shown in Fig. 1; Fig. 5, a plan of the paper-carriage and inking-ribbon device;

Fig. 16 is a detail view showing the raised portion of the threaded bar for operating automatically the detachable connection. Fig. 17 is a detail of the said connection.

Similar numbers and letters refer to similar parts throughout all the views.

The bed-plate 1 supports all the mechanism and has a vertical bearing 2 rigidly connected to or cast with it. Into this bearing the journaled lower end of post or stud 3 snugly fits, but so as to turn about its axis readily and rests on its shoulder 4. Near the upper end of this stud 3 the screw-rod 5 passes through, having a nicely fitted shoulder 6, which is drawn tightly to the stud'by means of the nut 7. From the shoulder 6 to the screw-thread 8 the screw-rod 'is turned to fit the hub 9 of the main wheel 10, but loose enough to allow thewheel to turn easily. To the hub 9 the sleeve or tube 11 is rigidly connected also to the collar 12, which is fitted to turn on the screw-rod. The collar13,madefasttothescrewrod, holds the tube and its appurtenances in place. Two disks 1 1 15, having flanges a a and hubs b b fitted to turn easily on the tube 11, have the cylinder 16 firmly attached, and have openings 0 c to admit the paper clamping device, which consists of two bars 17 18 Wit-h upright ends da, one bar 19 with a slot from f to f two regulating-screws g g,a spring h, and the T-headed uprights vlj k Z, hinged at their bases to bar 17, and passing through apertures having pendent shoulders m n 0 p in bar 18, which work against corresponding shoulders on the T-headed uprights, the bar 18 being held down to the shoulders of the uprights in the present case by means of pins passing through them just' above the top of bar 18. The bar 19 may be made fast to the cylinder 16 in numerous ways. In the present instance it is held by pieces AB, screwed to itself and the cylinder.

The screws 9 g work in threads in bar 19, pass through slots q 7' in bar 18, and work loosely in and have collars both below and above bar 17, for the purpose of allowing the T-headed uprights to be raised or lowered at pleasure by turning these screws. The bar 18 is jointed at s to allow the teeth zfto be engaged or disengaged with the catch a. The spring h is adjusted to press the teeth 25 to the catch it. In order that the teeth i may at all times be able to fully engage with catch u, the pendent shoulders on bar 18 are lined with some elastic material, as rubber. The slots (1 and allow the barlS to have amotion backward and forward in the direction of its lengths, for purposes which will be shown farther on.

The pin 20 passes loosely through bar 19, the guide o,and the slot w in tube 11, having a tight collar 0 for a spiral spring, which holds it (the pin) in engagement with the screw to abut against. This pin also has a recess D, which comes in use in this wise, to wit: Suppose the machine ready to use. As the operator begins, the top of the paper-carriage revolves toward us as we look at Fig. 1. The tube 11 and wheel 10, being rigidly connected and having a rotary motion,carry the paper-cylinder around with them by means of pin 20 passing through the slot but as the paper rotates, pin traverses the screwthread the whole length, passing along the slot 20. The bottom of the last half of the last thread on the back side of the screw in Fig. 1, and hence not seen, rises gradually till it lifts the pin up to the point E, this point being bossed to make it a little higher than the surface of the threads. At this point the recess D is raised so as to be made to engage with the end of bar 19 by the action of the spring F, when the operator removes the written sheet (in a manner to be described further on) and pushes the paper-carriage back to the position shown in Figs. 1 and 5. Here the head of pin 20 strikes against wheel 10 and disengages the recess D from bar 19, and the spiral spring forces the pin down to the screw-thread ready to start the writing of another sheet. It may sometimes be necessary to rotate the cylinder independently of the sleeve, and to effect this purpose the pin 20 has a second recess D, which will. engage with the end of the bar when the lower end of the pin is raised entirely out of the slot. I do not wish to confine myself to the use of a stationary screw, though this is used preferably.

A standard 21 has an index pointing down to numbers on the inside of wheel 10. Fig. 15 shows some of these numbers. The purpose of this index is to enable the operator to revolve the paper-carriage forward any given number of spaces, noting by the eye the movement of the paper-carriage as the space-bar is struck.

Stud 3 has an arm 22 bent around to receive the end of the key-shaft 23, to which a clock-spring 24: is fastened and covered by a box made fast to arm 22. Wheels 25 and 26, with pawl, are arranged entirely similar to clock-work. 1 V heel 25 gears into 27, which is made fast to the hub of wheel 10, the object of this clock-work being to drive the papercylinder.

Stud 3 has a second arm 28 terminating in an upright 29, which supports the escapement-lever 30 and its accessories. The escapement-lever is worked by the lever 31, through connecting-bar 32 and knee-lever 33, which may be connected to the spacer-bar 34 by a lever, or, as in the present instance, by a strap 35, passing over pulleys 36 37, Fig. 5, and being attached at G, Fig. 6, to a projection on the lower side of the spacer-bar, thus compelling an upward motion of the horizontal arm of the knee-lever when the fingerbars 38 39 810., press the spacer-bar 34 downward, and at the same time pushing the lower branch II of the escapement-lever fully into the space between the teeth, as shown in Fig. 8. At this stage of the operation the upper branch I is wholly disengaged from the teeth, and being hinged at J and having a spring K on the under side is pressed up against a stop L, which is so placed as to allow the point of branch I to pass between the teeth at M when branch II recedes. \Vhen branch II becomes wholly disengaged from the teeth, branch I becomes wholly engaged, as shown in Fig. 9, and wheel 10 has revolved a distance equal to the space between two teeth, being arrested at this point by the stop N.- On pressing the finger and spacer bars down to print a character or letter the point of branch II slides along the under side of the tooth till it assumes the position in Fig. 8, holding the papencarriage perfectly still all the while. On letting the finger and spacer bars up the spring 40 moves the escapement-lever and its appendages to the position shown in Fig. 9. In Figs. 2, 5, and 6 the spacer-bar is shown at half-stroke, causing both arms of the escapement-lever to stand in contact with half the length of the teeth. A joint 0 in the escapement-lever allows the upper branch I to be disengaged from the teeth at the same time the bottom branch II is, when the paper-can riage can be revolved any desired distance backward or forward, where it may be held at pleasure by a pin on stud 21.

Two margins of the paper come together under the T-heads i9 Z, as will be seen further on. It is obvious that these margins and T-heads should not be struck by the types as they pass under the inking-ribbon. To effect this result, a few teeth are left oif wheel 10 at the proper point, as at P, Figs. 5 and 10, causing one stroke of the spacer-bar IIO to move the paper-carriage forward the required distance. To obviate extra wear resulting from the blow given by the sudden stopping of the paper-carriage and wheel 10 after revolving this unusual distance, the branch I and tooth Q are broadened to the left. To enable branch H to operate while the space without teeth passes it, its extremity is broadened to the right, anda piece R with teeth is secured to the right side of wheel 10. Connecting-bar 32 is loosely secured to lever 31 and hanger 41 by rivets or bolts; but its connection with theknee-lever 33 is by means of a pin fast in 32 and loose in 33, or it may be fast in 33 and loose in 32, the object being to have it readily engage with or disengage from the knee-joint.

From the foregoing description it is obvious that the paper-carriage and all its appendages in front of the knee-lever are permanently connected directly or indirectly with stud 3, and consequently may be swung around to the right from under the inkingribbon. IVhen this is done, rod 32 disengages from the knee-lever, but is prevented from lowering by the hanger 41, which is the same length from pivot to pivot that 31 is, thus always holding rod 32 in position to engage with the knee-lever when the paper-carriage is swung to its working position. A stop 42 prevents the paper-carriage from swinging too far to the left, while a pin 43, lowered into the bed-plate 1, holds it from moving to the right.

The inking-ribbon motor consists of two reels 44 and 45, which wind and unwind the dle 47.

ribbon NV alternately. Reel 44 is rigidly attached to pawl-wheel 46 and turns on a spin- Reel 45 is rigidly attached to pulley 48 and turns on a spindle 49. The pawl 50, having a projecting limb S, is set tight on shaft 51, which works loosely in bearings 52 53. A spring 54 is arranged to keep the pawl pressed against the teeth of the wheels. hen the pawl works in wheel 46, its limb S works between two projecting parts T U of the spacer-bar, which keep the pawl from moving either to the right or left. By having a shoulder on shaft 51 abut against bearing 52 the projecting part U may be dispensed with. When reel 44 becomes full, the inking-ribbon must be wound on reel 45. To accomplish this, seize the button 55 and turn the shaft 51 forward till the point S of the pawl falls below the projection T. Then pull the shaft to the left till the point S will pass between projection T and bearing 53. The

, pawl will now work in wheel 56, which is fast to pulley 57. Both wheel 56 and pulley 57 run loose on spindle 47. A crossed belt 58 connects pulleys 57 and 48, thereby giving motion to reel 45, reel 44 being left free to unwind. The spindles 47 and 49 are made fast to an arm 59, which projects from stud 60, bolted to the bed-plate I. Arm 59 has a projection 61-, through which a prodding-pin V, with fiat head and'sharp point-works.

The object of this pin is to mark the paper when it becomes necessary to remove the paper-carriage for any purpose in the midst of the writing of a sheet, the marking being done by striking the head of the pin and driving the point into the paper. A spring 62 carries the pin up after the blow. By marking the paper in this way the papercarriage can be removed and returned to the exact point and the printing or writing be continued in an unbroken manner. The spacer-bar in the present case is attached to studs 63 64, which are bolted to the bed-plate; but any other convenient method may be used. Springs 65 66 keep it pressed up against the finger-bars, which may be connected with the bed-plate in any convenient manner.

The T-heads z'j 70 Z are designed to hold and release the paper at the pleasure of the operator. To this end I prepare the paper, first, by cutting one sheet just long enough to reach from one 'edge of the slot ff around the cylinder to the other edge of said slot, then another sheet just long enough to cover the first, and so continue till I have, say, a dozen sheets so out. Secondly, I slit up tagpieces on the edges under where the T -heads will come and bend them back alternately in opposite directions, as shown in Figs. 12 and 13 at 67, 68, and 69, the tags all being bent downward. Fig. 3 shows how alternate tags may be bent up and down. Thirdly, I place the sheets together in their order, put tacks 7 O 71 72, 820., through one edge to hold the sheets from slipping on each other, and press them around a cylinder spiral or otherwise a little smaller than the paper-carriage cylinder. This is done to set the paper so that it will cling to the paper-carriage cylinder and not have a tendency to come off when the T-heads are loosened for an instant on the removal of a printed sheet. The paper, being thus prepared, is slipped on the paper-carriage cylinder and the T-heads are made to press down on the top sheet over the tag-spaces by moving bar 18 in the proper direction. Take Fig. 7. Suppose there are two sheets on the cylinder. Bar 18 is pulled to the left allit will go,

and the T-heads press down on the top sheet at 74. Now toremove the outside sheet, push bar 18 to the right all it will go, and the T-heads will strike under the sheet at 74 and occupythe position shown in Fig. 1. The outside sheet is now free and may be removed. I proceedin the same manner to remove any number of sheets.

To facilitate the removal of the sheets from thepapercarriage the forceps 75 are provided, having a pad 76 at each end lined with some roughened material 77, as rubber. The rivet in these forceps is prolonged upward, having a T-head 78, which terminates at each end in journals which have bearings in two branches of a standard 79. The object' of this construction is to allow the pads 76, &c., to be raised and lowered at pleasure, while the forbranches 81 enter a groove 82, provided for them, for the purpose of holding the papercarriage from moving either way while the operator manipulates the bar 18. Thus the operator seizes the forceps wit-h his left hand, loosens the paper by moving bar 18 in or out, as the case may be, with his right hand, then elevates his left hand, bringing the pads of the forceps down to the bed-plate, carrying the paper with them and droppingit through the opening 83. A chain 84: holds the forceps from opening too far, and two springs 85 86, with catch-heads, prevent them from closing voluntarily or rising too high.

It is obvious that the line of printing will run slightly diagonal across the sheet. For parties who obj ectto this I substitute in place of the screw-rod 5 a rod having the threads cut in rings which lead into each other, as shown along the line 87, Fig. 4, placing this rod in such a position as will cause the pin 20 to cross line 87, while the space of vacant teeth in wheel 10 passes branch I of the escapement-lever, thus giving with one stroke of the spacer-bar all the motion of the papercarriage in a direction parallel to its axis,which is required for one line and space in writing or printin This feeding device is shown as applicable to a short-hand machine whose marking-keys are provided with combination, types and strike downward; but it can be used in writing-machines having keys striking upward by placing the inking device below the cylinder.
